23 * This code provides some support for doing STUN transactions.
24 * We send simplest possible packet ia REQUEST with BIND to a STUN server.
26 * All STUN packets start with a simple header made of a type,
27 * length (excluding the header) and a 16-byte random transaction id.
28 * Following the header we may have zero or more attributes, each
29 * structured as a type, length and a value (whose format depends
30 * on the type, but often contains addresses).
31 * Of course all fields are in network format.
33 * This code was based on ministun.c.
